SKF NU313 ECP/C3 Cylindrical Roller Bearing

The SKF NU313 ECP/C3 Cylindrical Roller Bearing is a precision single-row cylindrical roller bearing manufactured by SKF, the world's leading rolling bearing producer founded in Gothenburg, Sweden in 1907. Designated NU313 ECP/C3, this bearing features 65 mm bore (d), 168 mm outer diameter (D), and 33 mm width (B), giving it a compact yet robust geometry suited to heavy-duty industrial rotating equipment. This single-row cylindrical roller bearing (ECP/C3 polyamide cage) offers very high radial load capacity and is separable for easy mounting, with the NU3-type ribs determining axial guidance. It carries a basic dynamic load rating (C) of approximately 199.0 kN and a basic static load rating (C0) of approximately 213.5 kN, with a reference rotational speed of around 2500 r/min depending on lubrication and mounting conditions.

The NU313 ECP/C3 is engineered with SKF's high-grade chrome steel raceways, precision-ground rolling elements and optimised internal geometry to reduce friction, running temperature and noise. This makes it particularly well suited to the demanding thermal conditions of the Saudi Arabian climate, where ambient temperatures regularly exceed 50 degrees Celsius and airborne dust and sand place severe demands on sealing and lubrication. SKF's seal and clearance options help maintain a clean lubricant film, extending grease life and reducing unplanned downtime in desert and coastal Eastern Province environments where humidity and salt-laden air accelerate corrosion.

In Saudi industry the NU313 ECP/C3 is widely specified for rotating equipment at facilities such as Saudi Aramco (Abqaiq Plants gas-oil separation) and Saudi Aramco (Khurais water injection facility). Typical duties include electric motors, pumps, fans, gearboxes, compressors and conveyor systems across the oil and gas, petrochemical, desalination, power generation and mining sectors. SKF bearings are accepted on major Saudi approved vendor lists including the Saudi Aramco AVL, and are SASO compliant for use throughout the Kingdom.
